As electric bikes (e-bikes) continue to grow in popularity across Hawaii, it’s important to stay informed about the latest regulations designed to keep riders safe and ensure responsible use on our roads and trails. Recently, Bill 52 was introduced to address key safety concerns and update Hawaii’s e-bike laws, setting clear guidelines for riders, manufacturers, and local authorities.
Let EBikes Hawaii walk you through the new safety regulations, including the class system for e-bikes, age restrictions, and helmet requirements under Bill 52. Whether you’re a seasoned rider or new to the e-bike world, understanding these changes is essential to riding safely and staying compliant with state laws.
In Hawaii, electric bikes are categorized into Class 1, 2, and 3, each with distinct capabilities and legal considerations.
